Building construction



Patented June 17, 1930 WILLIAM C. KOCH, OF ST. PAUL, MINNESOTA BUILDING CONSTRUCTION Application filed June 27,

This invention relates to an improved method of constructing dwellings and other buildings, particularly by the use of brick or other masonry as the outer shell of the walls and a suitable concrete as a backing or sustaining body.

It is my object to provide a novel method of constructing walls whereby great strength and durability is imparted thereto, and a wall having high heat insulating qualities is produced.

A further object is to reduce the cost of masonry and concrete buildings by eliminating the forms or false works usually required where concrete is employed and also by minimizing the time required for the erection of the walls.

The invention will be best understood by reference to the accompanying drawing in which Figure 1 is a horizontal section through a portion of a wall formed by my improved process; Fig. 2 is a fragmentary external elevation of the wall; Figs. 3 and 4 are fragmentary internal elevations with plaster removed showing the spacing members in connection with different types of plaster supports or laths; and Figs. 5 and 6 are plan and side elevations respectively of suitable spacing members for use in constructing the wall, Fig. 6 also showing suitable metal lath in vertical section.

As illustrated, my improved wall comprises an outer shell 7 of brick or other suitable masonry, spacing members 8, plaster support 9, covered with plaster 10, and a concrete sustaining body 11. The spacing members 8, as shown in Figs. 5 and 6, are preferably constructed from suitable heavy gauge wire which is bent to form a loop 12 and then extended in a plane perpendicular to the loop- 12 to form abutments 14 for engagement with the inner surface of the wall 7. From these abutments 14, the member 8 extends perpendicularly a distance about equal to the thickness of the concrete portion of the wall, and 7 its normally inner end is formed with a fork 13 for engaging the plaster support 9, the wire being crossed at the point 15 to form a stop to engage the outer surface of the plaster support 9.

1927. Serial No. 201,618.

Any suitable plaster support or backing may be used such as the perforated metal plate 16 shownin Fig. 3, or the expanded metal lath 17 shown in Fig. 4. The plate 16 has openings 19 through which the forks 13 may be inserted, and the lath 17 is of the common type formed with diamond shaped openings.

In the construction ofa building, a suitable foundation is formed, and then the brick wall 7 is erected in the usual manner upon the foundation. This wall is sufficiently self sustaining when made approximately four inches in thickness. During the construction of this wall, spacing members 8 are inserted in placed relation, vertically and horizontally, as indicated in Figs. 1 and 2. After a row of bricks has been laid, the spacing members 8 are embedded in the mortar between bricks with the loops 12 in ahorizon- 2' tal plane and the abutment members 14 engaging the inner surface o-fthe brick as indicated. In this manner a self sustaining outer shell of the building is constructed and the spacing members 8 are firmly held therein when the mortar has set. During theerection of the outer shell, the mill work, such as door and window frames, (one of which is indicated by the numeral 18 in Fig. 1) is M mounted in the wall and allowed to project from the inner surface thereof.

After a section of the wall or outer shell 7 has been constructed as described above, the next step in the operation is to secure the F, plaster support 10 to theinner ends ofthe members 8, leaving a space between the outer shell and the plaster support. To accomplish this, it is onlynecessary to extend the forked end of each spacing member through an opening 19 in the type of plaster support .shown in Fig. 3, and then to bendthe ends laterally, or to secure one ofthe wires. of the metal lath shown in Fig. 4 between the forked ends as indicated in dotted lines in Fig. 6.

The crossed portion 15 of the wire furnishes a stop or indicates the proper location of the plaster support relative to the wall 7. After insertingthe forked ends 13 they are bent laterally to engage and hold the plaster support 10 firmly in proper spaced relation to ploy a concrete of light weight and having good insulating quality, such as that which contains a large proportion of-argi-ll-ac-eous material burned at temperatures of from 1700 to 2200 degrees Fahrenheit in place of sand and crushed rock or gravel. Such concrete of light Weight may'be poured in a section of the wall of a few feet in height so that excessive hydro-static pressure will not be applied to the inner shell. l Vhen one section of concrete has set, the other sections may be poured successively until the wall is complete. Preferably the entire inner shell of the wallshould .not be constructed until after the lower portion of the concrete 11 has been poured. Where water .pipes or other conduits are to be embedded in the wall they are constructed before pouring the concrete. The time required .to construct a building is reduced by my improved method because the masons laying the brick or other material for the outer shell may be employed upon one portion of the wall while workmen constructing the inner shell and pouring concrete may be employed on other portions simultaneously. Further, a large part of the frame of the building, such as studding, is eliminated as well as all false works for retaining the concrete. The spacing members 8 insure uniformity in the spacing of the outer and inner shells. Thus when the outer shell-has been properly constructed the location'of the inner shell and thickness of concrete :is accurately fixed by the spacing members.

Having described my invention what I claim is new and desire to protect by Letters Patent is:

The method of constructing buildings, which consists in erecting arthin, outer, permanent but only temporarily self sustaining shell, consisting of a single thickness of face brick and securin between said brick a multiphcity of spacing members arranged to project inward "therefrom, :then securing to said spacing members .in spaced relation to '55 said outer shell, an inner shell consisting of a foraminous plaster support constituting a permanentportion of the wall, then applying plaster to said inner shell and allowing the same to harden with portions thereof projecting into the space between said inner WILLIAM C.
